To all whom, t may concern,.-

Be it known that we, LUCIEN vH.' HANDY, residing in the city and county of San Francisco, and CHARLES S. I-IosFoRD, residing at Berkeley, Alameda county, State `of California. citizens of the United States, have invented certain new and useful Improvements in Burglar- Alarms and Sash-Locks; and we do hereby de- Clare thefollowing to be a full, clear, and exro act description of the same.

Our invention relates to the class of burglaralarms and locks particularly intended for window-sashes. f

It consists in the novel construction, ar-

rangement, and combinations of parts hereinafter fully described and claimed.

The object of our invention is to provide a simple alarmand lock for window-sashes, one which can be readily and accurately adjusted Vzo to place, which will be inconspicuous, and

which will be effective in operation.

Referring to the accompanying drawings, Figure l is a perspective view of our device secured in. place and set for operation. Fig.

2 is a top plan in part section of same. Fig. 3 is an inner face view of the device, the bell being removed. Fig. 4L is a reversed side view of saine, showing in dotted lines the locking position of the tripping-lever.

3o A is an angle-bra eket forming the carryingplate for the several parts and constituting the means by which the device is secured to the Window-Casin g, (represented by B.) The securing means may be of any character, (here shown as screws 60,) which pass through the extremities of the bracket-arms into the casing. Pivoted by a pin or bolt c to the outer face of that arm of the carrying-bracket which lies at right angles to the plane of the window- The form or character of the cam impinge- 5o ment of tripping-lever C and set-bar E may be of any suitable nature. We consider the construction here shown a practical and simple means to effect the result. It will be seen that the end-of the set-bar projects through an inwardly-extendingflange a of bracket A and thatthe end c of the tripping-lever lies on the outer face of this flange and has in it a slot c2, the ends of said slot having the oppositely-inclined planes c3 lying directly be- 6o yond the projecting end ofthe set-bar. When the tripping-lever end c is central, the setbar E has ample room to be projected forward in the slot c2 without touching the inclined planes c3,- but whenthe lever end cfis rocked to 6 5 either side up or down one or the other of the inclined planes comes in contact with the setbar end, the edges of which are slightly rounded to ease` the contact, and said inclined plane rides down upon and forces backwardly the 7o set-bar. l.

The sliding set-.bar E is the means for controlling any suitable y alarm mechanism. When the bar is projected to its limit, it locks the alarm and keeps-it silent. lVhen the bar is forced back, it releases the alarm and permits it to become active. The form of alarm we here show and which we deem practical and simple consists of the ordinary gongbell F, secured to bracket A. Vithin the 8o casing or shell of this gong F is a spring, (unnecessary to show,) which spring'is wound by ing-bar G, and said bar is held projected by an arm g2, which projects from its forward end at right angles and enters a slot e in the set-bar E in such position that when the sety screwed to the Window-casing B.

bar is projected and is held so by the friction of its spring e the rear wall of slot e', engaging the arm g2, projects the locking-bar G and holds it proj ectcd, thereby causing its detent g to lock the alarm.

Now in order to operate the tripping-lever C by the movement ot the Window-sash D the other end of said lever has a means for engaging the sash in such manner that the movement of said sash will rock the lever on its pivotal center c. The best form of this engaging end is the sector-like head H, bearing against the face of the sash-stile and having such a surface, frictional or positive, as will cause it to be rocked by the sash in moving. We prefer to provide its engaging edge with the pins 7L, which Will take positive hold of the stile. In order, further, to constitute this sector-like end a lock as Well as ameans for moving the tripping-lever, its -engaging edge is made with a curved central portion h, struck from the pivot c as a center, and end portions h2, eccentric to said pivot. Thus when set centrally the first effect of the sash movement is to rock the head H, and thereby rock lever C to'actuate the alarm; but further movement of the sash when either eccentric end portion is reached results in a positive lock, for the lever C will then move no farther on account of the eccentricity of the portions h2. In order now to adapt this sashengaging device to the several adjustments necessary to apply the alarm and lock to various sizes of windows and casings, said head H is best formed as a separate piece and is connected adj ustably with lever C. Thus it has a shank h3, slotted over the pivot-bolt @,Which said bolt is provided with a thumb-nut c4.

The adjustment and operation of our alarm and lock are as follows: The bracket A is Then the thumb-nut c4 being loosened, the sash-en gaging head H is moved forward until its curved central portion h bears firmly upon the sashstile. Then the lever C being straight, so that its cam end c' is central, the thumb-nut c4 is tightened up suliciently to firmly hold the head H and lever C together and permit them to turn as one on pivot c. The alarm being Wound up, the set-bar E is projected, thus through the bar G locking said alarm. Now let the sash be moved up or down. The first efect is to rock the engaging sector-head I-l, which rocks the lever C. The cam end of lever C, by its inclined planes, either one, according to the direction of movement, forces back the set-bar E, thus relieving the arm g2 oi' locking-bar G. This bar G, under the infillence of its spring, will now be retracted and Will remove its detent g from the escapementpaWl and the alarm will sound and its warning will be incessant, requiring the attention of the occupant of the room to stop it. The next effect of the sash movement will be to lock said sash effectually by the eccentric portion h2 of the sector-head H; but the alarm will continue until the set-bar is projected again.

. A feature of decided advantage in this device is the angular carryin g-bracket A, ittin g the walls of the Window-casing, as shown. 1t lies close and Hat against these walls,enablin g the parts carried by its arm at right angles to the Window-sash to be as inconspicuous as possible, While the alarm-bell may be set far enough back to be wholly out of sight from Without. The operating parts on the firstnamed arm, even if observed by the intruder, may well be mistaken for some sort of lock or fastening alone which may in his opinion be broken by extreme pressure on the sash. This may lead him to the attempt, whereas if he saw the alarm-bell he might turn his attention to other possible entrances.
